FILM-CLIP.

Specification of Letters Patent.

Patented Mar. 30, 1920.

Application filed August 1, 1919. Serial No. 314,658.

To all whom it may concern:

Be it known that I, JOHN G. HARTLIEB, a citizen of the United States, and a resident of the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented anew and Improved Film- Clip, of which the following is a full, clear, and exact description.

This invention relates to improvements in film clips, an object of the invention being to provide a clip which securely clamps the two ends of a film holding the ends apart and permitting the film to be easily supported in the developer or wash during process of development.

A further object is to provide a clip of the character stated which when pressure is applied to one member serves to open or separate the clamping jaws to permit the insertion of the film ends and when released securely clamps and holds the film.

A further object is to provide a film clip which can be manufactured and sold at a reasonably low price and which will most efiiciently perform the functions for which it is intended. \Vith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in claims.

In the accompanying drawings.

Figure 1 is a perspective view showing the clamping jaws separated.

Fig. 2 is an edge view of Fig. 1.

Fig. 3 is a view similar to Fig. 2 showing the parts in normal position.

Figs. 4 and 5 are plan views illustrating the blanks from which the clip members are made.

Fig. 6 is a plan view of a modification.

My improved clip comprises two memhers I and 2, both preferably of sheet steel although various materials may be used which are capable of the results desired. Member 1 is provided in one end with a longitudinal recess 3 forming a pair of gripping jaws fl: and the other end of the member 1 is made with recess 5 in the sides thereof, forming a gripping jaw 6 at the end of the member. The member 1 is bent as shown clearly in Figs. 1, 2, and 3, and the ends of the member are crossed with the narrow portion 15 between recesses 5 positioned in the recess 3 in the opposite end of when these tongues are bent the member. To properly shape the member 1 it is made with bending points 16 and 17 at one end and bending polnts 1'9 and 20 at its other end, in the strips 18, which form the jaws 4, so that the jaws 4: and 6 when in normal position are substantially parallel to each other as shown in Fig. 8. The member 2 is bent on the lines 7 7 at opposite sides of its center, to form a pair of jaws 8, 8, one end of the member 2 having a tongue 9 projecting through the slot 10 in member 1 and the other end of member 2 having a pair of tongues 11 projecting through slots 12 in member 1 and downwardly they securely hold the members 1 and 2 together.

To facilitate the gripping action, the jaws 4 and 6 are preferably provided with studs 13 stamped therefrom which register with openings 14 in the member 2 and prevent slipping of the wet film when the latter is engaged.

In Fig. 6 I have illustrated a modification in which a member 21 may be utilized to replace the member 2 of the preferred form. In this modification the member 21 is formed of two parts 22 having a hinged connection 23 to form a pair of jaws.

Various other slight changes might be made in the general form and arrangement of parts described'without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and all alterations as fairly fall within the spirit and scope of the appended claims.

Claims:

1. A film clip, comprising two pairs of jaws normally together, and a resilient handle connected to two of said jaws and adapted to move the jaws apart.

2. A film clip, comprising two pairs of relatively fiat jaws normally together, and a resilient handle connected to two of said jaws and adapted when compressed to separate the jaws.

3. A film clip, comprising two members, one member of resilient material bent between its ends forming a handle, said mem her at its ends forming jaws, and the other member connected to the first mentioned member and forming jaws cooperating with the first-mentioned jaws.

jaws, and studs on the other of said jaws registering with the openings.

' 6. A film clip comprising two members, one member composed of a strip of spring metal having a longitudinal recess in one end and having recesses in its side edges adjacent its other end, forming a narrow portion, said ends crossed with the longitudinally recessed end receiving therein the narrow portion of the other end, the second member bent at two points at opposite sides of its center, one of said members having slots therein, and tongues on the other of said members secured in said slots.
